Analyzing the state of a technical system with respect to requirements compliance

Abstract

The following refers to a computer-implemented approach for evaluation of contractual requirements in view of a technical railway system, namely whether the latter complies with the requirements. The technical railway system and is modeled in case of non-compliance the system is modeled and contractual requirements are modeled in one common model. The generated model is analyzed in order to calculate control instructions for matching the same.

AI Technical Summary

Benefits of technology

The patent text describes a method for modeling a technical system and its requirements using software and hardware. The model allows for the analysis of the technical system and the identification of important requirements. It can also process time-dependent criteria and complex interrelations between different aspects of the technical system. The technical effect of this method is improved performance monitoring and evaluation of the technical system based on its requirements. The method can detect and resolve inconsistent input values, and it is accessible as a web service on multiple devices. The invention allows for the identification of opportunities and the optimization of business process layouts, as well as the provision of a realistic valuation of the technical system.

Problems solved by technology

In case of non-compliance, for example caused by decreased performance, costs and penalties may arise.

Also, the different requirements may be complex and show interdependencies.

In a complex technical system, like a railway system, system performance needs to be detected (including decreased system performance, for instance through the effect of random failures).

In state of the art systems, the mapping between the technical system and the requirements was analyzed manually, which leads to the risk of inadequate, incomplete or flawed implementation and, therefore, erroneous analysis results.

The impact may comprise penalties or costs for non-compliance with requirements.

The impact may also comprise negative side effects with other systems.

This is due to the fact, that non-conformance with contractual requirements by system developers, like the applicant, may result in severe penalties and other costs over long time periods, besides potential loss of reputation.

Failure to properly quantify the financial impact and risk (valuation) of (non-conformance with) contractual requirements may significantly reduce the profitability of projects or lead to lost opportunities.

The impact result data may also quantify the impact in terms of inefficient use of operational resources, adverse environmental impact, etc.
